-To all whom it may concern:

' Be it known that we, JULIUS BRENZINGER and PAUL I-I. LANGE, citizens of the United States, and the former a resident of Fairfield, in the county of Fairfield and State of Connecticut, and the latter a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Eject ing Mechanism for Hollow Bodies, of which the following is a specification.

This invention relates generally to heading machines, and has for its main object and feature the detection of the absence of a' cover from position on abody or container and the consequent removal of the body from the machine. If such absence is not detected and the body is not removed the body continues through the machine and the spoiling said body.

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which Fig. 1 is a front elevation of a heading machine and associated parts embodying the invention.

Fig. 2 is a plan view on the plane ofline 2-2 of Fig. 1. i

showing the position of the parts when a cover is in placeon-the body.

N Fig. .7 is a front elevation of Fig. 6- with the'turret in section. V

\ The headingmachine structure itself may be of anylsuitable character such as the well-- known ax A'ms heading machine. The

in-"feed and out-feed means may likewise be 50 ofany suitable construction but are preferably of the character disclosed in applicaseaming operation is performed thereby tion Ser. No. 602,505 filed November 22, 1922.

In its general construction the machine here comprises a step-by-step rotatable turret 1 having pockets 2 which slide the bodies over'table 3 and thus move said bodies in an orbit through the machine from in-feeding station 4, to ejector station 5, to seaming station 6 and tmdischarge station 7. In the present instance the bodies intended to be acted upon are square or non-round oblong bodies 8 andare fed into the machine. in a recumbent' position by in-feed means 9. They are then up-ended by means of spider 10, after which pusher 11 moves the bodies into pockets 2 of the turret. After abody has traversed the orbit it is removed from pocket 2 at station .7 by discharge means 13 which eventually push it on out-feed means 12.

Located adjacent to ejector station 5 are the following means. 14 indicates a sta tionary support carrying an upright uide member 15, said sup ort having bus ings 16, 17, 18and 19. arranged in two pairs, an upper and lower one, the membersof each pan being connected by a webbing 20, as

shown. Slidingly mounted in this support are two vertical reciprocating rods 21 and 22 which are seated respectively in bushings 16 and 18 and 17 and 19. Mounted fast onrod 21 is a bracket 23 which has'a bushing 24 slidably engaging vertical guide member 15 and mounted fast on rod 22 is a detector '35 which consists of abushin 25 carrying an 'arm. 26 at the outer end 0 which is pivotally mounted a lever 27 normally held atright angles to arm 26 by means of spring 28 but capable of yielding in a manner presently to be described. One endof the lever 27 carries detector finger 28 which is in the form of a downwardly projecting rod. Mounted fast on rod 22 is a sleeve .29 that carries an arm 30 provided with a sleeve 31 slidably and loosely engaging vertical guide 15. Any suitable means may be provided for verticallyreciprocating rod 2l,'in

this instance consisting of cam 32 which actuates bell crank 33 pivoted at 34 and to which is pivotally connected links 35' which latter are also pivotally connected with rod I detector mechanism is sustained by bushing 24 and that an upward movement of bracket 23 and bushing 24 will raise the detector mechanism. Rod 22 is a rockshaft. and carries at its upper end an extension 36- on' which is supported a downwardly projectmg member 37 extending through arcuate slot 38 in webbing 20. Mounted loosely on rod 21 is a sleeve 38 carrying two members.

39 and 40. These members 39 and 40 together with sleeve38 are oscillated in a horizontal plane by any suitable means, in the present instance taking the following form. 41 indicates a cam actuating bell crank 42 pivoted at 34, the motion of said bell crank 42 being imparted to another bell crank 43 pivoted at center 44 by means of connection 45. 3 Bell crank 43 is connected with arm 46 of sleeve 38 by means of links 47 whereby an oscillating motion is imparted to sleeve 38 and members 39 and- 40.

The parts are so timed that as a container 8 comes in position at the ejecting station, bracket 23 and bushing 24 will clescend thereby also allowing the detector mechanism to descend. If there is no cover on the container or body, then detector finger 28 will be permitted to project into said body and by this movement will carry rockshaft 22 and member 37- with it. Member 37 will thereby be brought into theplane of the oscillating arms 39'and 40 and by this time sleeve 38 is given a motion in such a direction as to cause arm 4O- to engage member 37 and thereby cause rockshaft 22 to turn in its bearings; and this, in consequence, imparts an oscillating motion to detector finger 28 thereby sweeping the body or container out of pocket 2 and down incline 49 of table 3. The parts now return to their original positions, bracket 23 rismg and arm 39 engaging with member 37 to turn, in the reverse direction, rockshaft 22 Wh1Cl'1;Ca.I'I'18S with it the detector mechanism. If upon the inward movement of the detector mechanism toward the turret any portion of said turret should engage wlth the'detector mechanism, lever 27 will yield in opposition to the action of spring- 28' and as soon as clearance between the parts is produced said spring 28' will re-- store lever 27 to its original position. If, during the next cycle of the machine, a

I cover, as 48, is in position onithe" body or within the body 8. In consequence of this, member 37 will not descend into the plane of arm 40 on oscillation of sleeve 38 and hence, when said sleeve is oscillated by the cam movement, its motion will not be transmitted to rockshaft 22 nor to detector 28 with the result that the container remains in position within pocket 2.

Ejecting mechanism for hollow bodies comprising: an upright rockshaft capable of an up-and-down movement, a detector member carried by said rockshaft to prevent downward movement of the rockshaft beyond a certain point when said detector member encounters a cover on a hollow body and to project within said hollow body when on its upstroke raises said rockshaft and which on its downstroke admits of the lowering of said rockshaft, and means for turning. the rockshaft efi'ective only when the detector member projects within the hollow body and permits the rockshaft to descend into the plane of said turning means.
